Understanding Short Term and Long Term Fuel Trim:
 
TTT

I don't think 138 is anyting to worry about and like Dave said it is doing what it is supposed to do. One thing to add. I get guys that call me all the time and say "my car is tto rich, my BLM is at 120" They don't seem to understand that their car is going to run the same at 120 or 128 that is only shows how much the ECM had had to adjust to get to the target programmed into the chip. It is the ecm telling you "hey you were a little rich but I fixed it" It is when you get to the upper or lower limit that you really have problems. Of course closer to 128 is better when we transition from cell to cell so we do not have stumbles from sudden fuel changes but overall guys get too excited about this sometimes
